Problems with units:
I was playing an easy game but the monsters are way to strong for NORMAL units.
I had a Unit with 55 attack against a 16 attack monster. Monster did 16 dmg and i did only 5 dmg... 3 monsters attacked in one turn and that unit was dead.
If the units are that weak the time to make them is way too long.
e.g monster had amor of 2 and i had armor of 6 for that unit.
